It's been over a year since the last time I reviewed (1, 2) the Linux distribution that I use most of the time, Arch Linux. Since then, while the distro-specific innovations have slowed a bit down, maturity and stability has emerged.

There's also to add that the community is getting bigger and bigger, the forums are crowlyng with people willing to help, develop and test.
I was a gentoo user, so the change wasn't that hard, from a ultra-optimized distro to a i686 optimized, the speed is the same (faster on the init scripts of arch, openoffice,..). So if I wanted to compile critical parts of my distro I could do it using ABS (Arch Build System).
There's also another thing missing, aur.archlinux.org (Arch User Repository) is a wonderfull place to get PKGBUILDS (bash script installation file) for other packages unavailable from current,... there's also a package manager for that to named aurbuild that makes que build easier without having to go to the site and search, and for searching... there's qpkg (available in aur).
So, it doesn't have fancy wizards like mandriva or suse, but it has A LOT of packages ready to install, there's also a graphical installer for pacman named pakman but it is still in development (search the forums at bbs.archlinux.org), so arch linux has become my distro of choice.
